Description
The LaRue LT101 solves a common headache: your red dot, holographic sight, or scope mount sitting too low or bridging awkwardly across the receiver and handguard. This riser adds 5/8" of height above your host rail, which brings the optic up to a more natural line of sight and makes for a noticeably more comfortable cheek weld. At 5.5 inches long with 13 MIL-STD-1913 lug spaces, it gives you plenty of real estate to position an optic, a magnifier, or a combination of the two on a single platform.
What the LT101 Riser Brings to Your Setup
LaRue machines the LT101 from bar-stock aluminum and finishes it in matte black anodizing, so it holds up to the kind of abuse a working rifle sees. The standout feature is the dual QD lever system. Flip the levers, pull the riser and whatever's mounted on it, then reinstall later and your zero comes back. That's the reputation LaRue built, and this riser carries it. If you swap optics between rifles or break your gun down for transport, that return-to-zero reliability is the whole point.
Mounting the LaRue LT101 More Than One Way
Here's where it gets useful beyond just lifting optics. Plenty of folks run the LT101 on the underside of the handguard to hang vertical grips, weapon lights, and other accessories where they want them. The cantilever design also keeps your optic mounted fully on the upper receiver instead of straddling the gap between the receiver and rail, which is one of those small details that helps accuracy stay consistent.
Bottom line, this is a purpose-built riser for anyone running an AR-pattern rifle or similar platform who wants their optic at the right height without giving up the ability to pull it and put it back on the money. It's a piece of gear that does exactly what it says and gets out of the way.

Frequently Asked Questions
How much height does the LaRue LT101 add to my rail?
The LT101 raises your optic 5/8" above the host rail. That extra height brings a red dot, holographic sight, or scope up to a more natural line of sight for a better cheek weld and sight picture. It's a popular amount of lift for AR-pattern rifles running magnified or non-magnified optics.
Does the LT101 really hold zero when I take it off and put it back on?
Yes, the dual LaRue Speed Levers are engineered for return to zero, so you can remove the riser and reinstall it without losing your zero. This is one of the main reasons people choose LaRue mounts over cheaper alternatives. If you swap optics between rifles or break your gun down for storage and travel, that repeatability is the big draw.
Can the LT101 riser mount anything besides an optic?
It can. A lot of owners run the LT101 on the underside of the handguard to attach vertical grips, weapon lights, and similar accessories. With 13 MIL-STD-1913 lug spaces across its 5.5-inch length, there's room to get gear positioned exactly where you want it.
Will the LaRue LT101 fit my rail?
The LT101 clamps to any standard MIL-STD-1913 Picatinny rail, so it works across most AR-pattern rifles and other platforms with a Pic rail. Just make sure you have enough continuous rail space to seat its 5.5-inch footprint. The dual QD levers clamp it down securely once it's positioned.
